The negative electrode is a term commonly used in the fields of chemistry and engineering to refer to the electrode of an electrical device that carries negative charges. However, there are several alternative terms that can be used to describe this component. These include the cathode, the anode, the counter electrode, and the reducing electrode. In some applications, the negative electrode may also be referred to as the reference electrode, the working electrode, or simply the negative pole. Regardless of the specific term used, the negative electrode plays a critical role in many electrical devices, including batteries, fuel cells, and electrochemical sensors.
